What is the difference between a simile and a metaphor?

A simile and a metaphor are both figures of speech used to create comparisons, but they do so in different ways. A simile specifically utilizes the words "like" or "as" to directly compare two different things, making it clear that the two entities are not the same but share certain qualities. For example, saying "as brave as a lion" illustrates bravery through a direct comparison using "as."

On the other hand, a metaphor asserts that one thing is another, thereby suggesting a deeper equivalence between the two. For instance, stating "time is a thief" does not mean that time literally steals, but rather emphasizes how time can take away life's moments in a way that feels similar to theft.

Understanding this distinction helps in recognizing how each device can enhance imagery and meaning in language. The use of "like" or "as" in similes makes them distinct from the more direct assertions of metaphors, which can evoke stronger connections or associations.
